Ø Online Test
Ø Technical Interview
Ø HR Interview

B. QUANTITATIVE APTITUDE (32 Ques, 40 Minutes): Dis is d most scoring section in al d three as most of d questions ar 4m previous papers. understand d method of solving as dey may sometimes change d numerical value. Dat wil be more than enough, U even need not 2 solve RSAggrawal. If u ar not getting den "mug up d answer of dose" as some types of ques ar alwz repeated. Some of d questions which I remembered are as follows:

1.Father's age is 5 times his son's age. 4 years back the father was 9 times older than son. Find the father's present age.
Sol): 40 yrs

2.A person was fined for exceeding the speed limit by 10mph.another person was also fined for exceeding the same speed limit by twice the same if the second person was traveling at a speed of 35 mph. find the speed limit?
Sol): 15mph

3.A, B and C are the mechanisms used separately to reduce the wastage of fuel by 30%, 40% and 10%. What will be the fuel economy if they were used combined?
Sol): Method is (70/100*60/100*90/100)*100 = 37.8
So, economy = 100-37.8 = 62.2

4.Car is filled with four and half gallons of oil for full round trip. Fuel is taken 1/4 gallons more times in going than coming. What is the fuel consumed in coming up?
Sol): 2 gallon

Sol): Rs. 22500/- (plz refer previous paper 4r d method as I hv m own)

9.One fast typist type some matter in 2hr and another slow typist type the same matter in 3hr. If both do combine in how much time they will finish?
Sol): 1 hr 12 min

10.What are d Surfaces, vertices & edges of d cube?
Sol): 6,8,12

11.Which shape will be obtained by using these values of X & Y?

X Y
0 0.00001
10 1.02
100 1.72
1000 3.00
9999 4.72
Sol): Y= log10(X)

12. My flight takes of at 2am from a place at 18N 10E and landed 10 Hrs later at a place with coordinates 36N70W. What is the local time when my plane landed?
a) 6:00 am b) 6:40am c) 7:40 d) 7:00 e) 8:00

Sol): The destination place is 80 degree west to the starting place. Hence the time difference between these two places is 5 hour 20 min. (=24hr*80/360).
When the flight landed, the time at the starting place is 12 noon (2 AM + 10 hours).
Hence, the time at the destination place is 12 noon - 5:20 hours = 6: 40 AM

17. The size of a program is N. And the memory occupied by the program is given by M = square root of 100N. If the size of the program is increased by 1% then how much memory now occupied?
Sol): 0.5%

18. In d given series {"b v f q q m b v f m g v f f v f m b v f b g d v f a m v f v f f ...) How many v's are dere such that each v is followed by f next to it, if the f is not followed by q next to it?
Sol): try it out

19. the number 362 in decimal system is given by (1362)x , find d value of x
Sol): 6

27. Which is not a side of triangle?
a) (2,3,6) b) (3,2,4) c) (3,4,5) d) (3,3,3)
Sol): b

28. If g(0)= 1, G(1)=-1 ,G(N) = G(N-1)+G(N-2), then what is g(6)=?
Sol): -3 (not sure, just try it out)

29. Complete d series. 4,-5, 11, -14, 22, ---
Sol): -27

30. A file is transferred from one location to another in 'buckets'. The size of the bucket is 10 kilobytes. Each bucket gets filled at the rate of 0.0001 kilobytes per millisecond. The transmission time from sender to receiver is 10 milliseconds per bucket. After the receipt of the bucket the receiver sends an acknowledgement that reaches sender in 100 milliseconds. Assuming no error during transmission, write a formula to calculate the time taken in seconds to successfully complete the transfer of a file of size N kilobytes.
Sol): (n/1000)*(n/10)*10+ (n/100)....as i have calculated...~~! Not sure

Sol): To find A-C, We will find 2's compliment of C and them add it with A,
That will give us (A-C)
2's compliment of C=1's compliment of C+1
=11000101+1=11000110
A-C=11000101+11000110
=10001001
Now (A-C) U B is .OR. Logic operation on (A-C) and B
10001001 .OR. 00110011
The answer is = 10111011,
whose decimal equivalent is 187.

32. In Madras, temperature at noon varies according to -t^2/2 + 8t + 3, where t is elapsed time. Find how much temperature more or less in 4pm to 9pm.?

Sol): In equation first put t=9,
we will get 34.5......... (1)
Now put t=4,
we will get 27........... (2)
So ans=34.5-27
=7.5

33.34.35. Three questions were on bar graph. It was simple to attempt dere only. No need to practice

36.37.38. Last problem was based on Venn diagram. Figure was given & on dat basis 3 ques were dere.
Ex: a Venn diagram on no. of people who know only English, only French, only German, both English and French, French and German, German and English, know all the three.
->How many know English more than French?
->What % people speak all the three languages?
->What % people speak German but not English?

C. CRITICAL REASONING (12 QUES, 30 MINUTES): This is also another scoring section. it consist of three passages with four questions each .As I have found 4m previous paper till m exam date, dat all d passages are always given 4m d 5 model test papers dat are published in GRE Barron 12th edition. So I recommend u to plz solve dem all so dat it will be easy 4r u 2 attempt as dey may sometimes change d name or place in d questions. If u are unable 2 solve them den plz mug up d answers of d questions having 4 or more parts. Leave d remaining. Three passages which I got were:

In all dere were around 330 student who appeared 4r d test 4m m college & when results was declared , 248 were short listed 4r d further stages. I was one among d short listed students.
